Elecraft now sells the PowerWerx switcher after recommending them to any who asked (I did when I ordered my K3), which has switched adjustment for 120/240 V input. Line Frequency is not relevant. This is an RF quiet PS and uses the IEC power cord which you would get locally (standard desktop computer power cable). The PS is available from the usual sources. Mine is the one with the meters, but they are not really needed. I've owned it for almost three years without a hint of trouble.
An equivalent linear PS will be much larger and heavier.
